Answer:

Part a) The radius of cylinder a is
r=1\ cm

Part b) The radius of cylinder b is
r=2\ cm

Part c) The radius of cylinder c is
r=3\ cm

Explanation:

we know that

The volume of a cylinder is equal to


V=\pi r^(2)h

solve for r


r=\sqrt{(V)/(\pi h)}

case a)

we have


V=2,826\ cm^(3)


h=900\ cm

substitute the values


r=\sqrt{(2,826)/((3.14)(900))}=1\ cm

case b)

we have


V=2,826\ cm^(3)


h=225\ cm

substitute the values


r=\sqrt{(2,826)/((3.14)(225))}=2\ cm

case c)

we have


V=2,826\ cm^(3)


h=100\ cm

substitute the values


r=\sqrt{(2,826)/((3.14)(100))}=3\ cm
